ing the graduations of the teeth of a cross# out saw and the like; my device for the latter purpose including gauge pins adapted for insertionin the spaces between the sawteeth and adjustable across the working tace of the stock of my gauge, thereby to give the saw the required inclination relatively to the graduations and lead to be given the sawteeth, and also to give the cutting lines ot saw-teeth the desired curve towards the ends ot the saw. l

A further object of my invention is to pro` vide the stock of my saw gauge with a removable anvil, and to provide a series of the latter so that the cut of teeth may be given the desired lateral set against the surface of the anvil.

My invention also includes the specilic features hereinafter described, and illustrated in the accompanying drawings in which Fig. l is a perspective illustrating a pra ctical use of my combined gauge and set;` a portion ot' a cross-cut saw blade being shown in broken outline;

Fig. 2 is a cross-section approximately i taken on the broken line 2 in Fig. l, looking in the direction indicated by the intersection arrow;

Fig. 3 is a cross-section approximately taken on the broken line 3 in Fig. l, looking in the direction indicated by the intersecting arrow;

Fig. 4 is a plan section approximately taken on the broken line 4-4 of Fig. 3, lookinv in the direction indicated by the arrow;

ig. 5 is a cross-section of the stock of my saw-gauge, showing the stock as recessed 'for the insertion of an anvil-piece, a section or' which is shown in Fig. 6; and

Fig. 7 is a .diagrammatic section ot' the anvil drawn on a larger scale, with broken lines at the inclined face of the anvil illustrating variations'in the angles of such in.- clined faces; that is to say,a series of anvils being provided with differently inclined 'laces against which tohammer, and thus give the lateral set to the cutting points of the teeth, i v

The stock a is made with a recess o in which to insert an anvil-piece (Z. As inentioned, a series of anvils are provided, each anvil having an obliquei'ace as indicated at; a', and the series of anvils so provided varying from each other in the angles of such oblique faces. The anvil is atiiXed in place by a screw e.'

The head o of the stock is madewith loni gitudinal, dove-tail recess 'f in which'r is reciprocable a slide g 'provided' with va perpendicular arm ZL projecting over and beyondv the front or working face of the stoel-nso` as to serve torv gaging the length of the teeth as usual. The stock is made with pro- .jecting portions i, j, and z", j at both ends,

and therein at each end are journaled screws.

7i: andve. On each screw is threaded a nut, Z and Z and from each nut projects' a gauge-pin m (see detail Fig. 4) the pins km being preferably provided with heads n at their extremities, solas to hold the saw morev firmly. The gauge lpins m are adapted to be inserted in the spacesbetween adjacent teeth in the manner illustrated in Fig. l; and

by adjusting the screws c, c, so'as to placeA the nuts Z. Z in different planes, the sawblade may be inclined as desire-d i'or'gradun ating the length of the teeth; the saw-blade being shown in Fig. l by the broken outline 0. y

A clamp is lprovided-for rigidly holding the saw on the working face of the stoclrofv the gauge. The clampl is constructed as follows: Thru the stock a is transversely threaded a screw-shank y) provided with a clamping-head g, at its'end projecting beyond the working tace of the stock; and the screw shank p is provided at its other end with a handle r so that the screw o may be` rota-ted for applying the clamping head ql, as more clearly illustrated in Fig. 2, in which o designates the saw blade. As obvious, the clamping of the saw to theworking face of my sawgauge, serves to rigidly hold the saw in place while setting the points of the cutter teeth, and gaging the length of the teeth.

In using my device, the gauge-pins m are first given the adjustment required for posi-v tioningi` the saw relatively to the desired `graduation of the length of the saw teeth, and thus the saw 'is clamped 'to the working); face of my saw gauge, so as rigidly to hold the san7 in place while Working' thereon.

l claim:

l. In a saw-gauge, gauge-pins adapted 'for insertion in the spaces between the teeth ot' the saw to be gagged. projecting perpendicularly beyond the Workingv 'tace of the stock and independently adjustable across said Working lace thereby to position the saw relatively to the desired Agraduation ot the saw teeth.

2. In a saw-gauge, gauge-pins adapted for insertion in the spaces between the teeth of the saw to be gagged, projectingv perpendicularly beyond the Working` 'face of the stock and'independently adjustable across said Working' face. thereby to position the saw relatively to the desired graduation of the saw teeth, the extremities ot such gaugepius being' headed.

3. ln a saw gauge a screw joiu'naled at each end of, and transversely to the stock. a

nut threaded on each screw and a gauge-piu carried by @ach nut.

4. In a saw-gauge a clamp operable to clamp the saw-blade to the Working face ci the gauge stock, the ends of the stock having; projecting` portions, a screw journaled at each end of, and transversely to the stock in said projectingportions of the latter, a nut threaded on each screw and a gauge-pin carried by each nut.

A saw gauge comprising a slide mounted for longitudinal reciprocation in the head of the stock and having' a perpendicular arm projecting over and beyond the working face of the stock, gauge-pins adapted for .insertion in the space between the teeth of the saw to be gagged, projecting perpendicularly beyond the Working' face of the stock, means for independently adjusting said gauge-pins across said Working face thereby to position the saw relativeljv to the desired graduation of the saw teetln and inea-ns for clamping' the saw blade rigidly to the Workingtace of the stock.
